Sentra: A Sleep Safety Solution for Nocturnal Seizures

Sentra is a responsive sleep safety solution designed for people with epilepsy, particularly those who experience nocturnal seizures.
During epileptic seizures in sleep, individuals may be left in unsafe positions, increasing the risk of airway obstruction and delayed response. This project addresses that gap by combining detection and physical intervention within a single product.
The system uses sensors to monitor movement and head position during sleep. Based on this input, a layered airbag mechanism inflates in a specific direction to gently guide the head into a safer side position. This controlled and gradual movement ensures comfort while actively reducing risk during a seizure.
The design integrates soft materials, ergonomic form and embedded technology to function as a regular pillow in passive use, while enabling responsive support when needed. Sentra aims to provide reassurance to both users with epilepsy and their caregivers by offering a quiet, reliable layer of safety during sleep.
The project was developed through iterative experimentation to translate the concept into a working system. Initial prototypes focused on linking sensor inputs to controlled airbag inflation, establishing a condition-based response mechanism.
Alongside this, different materials, forms and construction methods were explored to achieve a balance between comfort and functionality.
The development process also involved collaboration, with a technician assisting with assembling the electronic components and a code developer supporting the programming of the system. This allowed the project to move from concept to a functional prototype, integrating both technical and design aspects effectively.
